Should there be a tag for the index
package? Being a rather generic term, it's hard to search for.
There's a tag indexing which covers generic index-related issues. This isn't necessarily appropriate for issues that are specific to one particular package.
There's a tag index with only two questions: How to display index entries on the same line as the text being indexed which is about LaTeX's built-in indexing facilities, and the question I just posted babel and index both redefine \markboth and \markright which is about the index
package.
If a tag is warranted, what should it be called? index-package?
A tag called index is likely to be used to mean indexing in general. In fact, should index be made a synonym of indexing to avoid being recreated?
[index-package]
seems the best idea still available. very slippery situation, but not unique. – barbara beeton Feb 11 '16 at 19:49
